7. Instructions
< Data exchange mode (Mode 0) >
When the instruction input comes ON with the operand B+1 is 0, the Data exchange mode (mode 0) is selected. In this mode, the
| #0 Frequency reference write (FA01) | |
| #0 Operation command write (FA00) | |
| #1 Frequency reference write (FA01) | |
| #1 Operation command write (FA00) | |
| : |
|
Scan | #n | Frequency reference write (FA01) |
#n | Operation command write (FA00) | |
| #0 Operating frequency monitor (FD00) | |
| #0 Output terminal status monitor (FE07) | |
| #1 Operating frequency monitor (FD00) | |
| #1 Output terminal status monitor (FE07) | |
| : |
|
| #n | Operating frequency monitor (FD00) |
| #n | Output terminal status monitor (FE07) |
The maximum Inverter number #n is specified by the operand B.
The scan execution status and the Inverter communication status are stored in the operand B+2 to B+7.
The command data table is specified by the operand A and A+1.
When the instruction input is reset to OFF, the operation is stopped after receiving the response from the Inverter currently communicating.

When the data for each operand are set as above, the following operation condition is specified.
•RW200=5 ⇒ The max Inverter number is 5. Therefore
•D1000=4 & D1001=2000 ⇒ D2000 is specified as the data table starting address.
